Novak Djokovic stormed into the quarterfinals of the Dubai Tennis Championships on Wednesday with a 6–2 6–3 thrashing of Tallon Griekspoor, swiftly returning to his best form at a tournament he has won five times.
A day after being taken to three sets by Czech qualifier Tomas Machac, Djokovic was back to his ruthless best and blasted past a shell-shocked Griekspoor to take the first set with two breaks of serve.
